In primary GBM cells, AA approximately doubles whole-cell KCa1.1 currents compared to control (Fig. 2B, 1.84-fold increase, n=14, p=0.001, two-tailed Wilcoxon test), whereas LCA does not induce an increase of the KCa1.1 current (Fig. 2A, 1.02-fold increase, n=16, p=0.63, two-tailed Wilcoxon test). This evidence concerns the gene KCNMA1 and glioblastoma.
